Valencia is a beautiful city indeed and public transportation is excellent too which also contributes to its&#39; environmental health<br /><br />It is nice to know that street pavements in Brazil have trees. In an Asian city that I visit regularly the roads which were once lined with trees have now been cut off in the name of road widening strategies!<br /><br />The advantage of planting native trees as in the case of Licania tormentosa is that they would inherently thrive in that region. As I was hearing about Licania tormentosa for the first time, I checked it out and found that many species of Licina have declined ain numbers and one has even become extinct in the recent years dur to deforestation. So the Brazilians are taking a two -pronged approach by planting these trees- increasing the numbers and promoting shade.Ruth Stephenhttps://www.blogger.com/profile/16568851633869445367noreply@blogger.comtag:blogger.com,1999:blog-2027286527219515017.post-2868899496698612532015-05-12T08:09:50.731-07:002015-05-12T08:09:50.731-07:00Very interesting, I would love to visit Valencia.
...Very interesting, I would love to visit Valencia.<br />In Brazil, street pavements commonly have trees to provide shade, and I guess this reduces heat island effects as well. One of the commonest used in the Mata Atlantica region is the oitizeiro (Licania tormentosa), as it is tough and drought resistant. Ironically, it is also one of the native trees of the region.Davidhttps://www.blogger.com/profile/17196473529075505697noreply@blogger.comtag:blogger.com,1999:blog-2027286527219515017.post-13332520990947762402013-02-05T11:08:18.272-08:002013-02-05T11:08:18.272-08:00I stand corrected- Rufus is still alive. :)I stand corrected- Rufus is still alive. :)Sarah Stephenhttps://www.blogger.com/profile/03305130267142945205noreply@blogger.comtag:blogger.com,1999:blog-2027286527219515017.post-17394596360796519842013-01-30T23:50:30.869-08:002013-01-30T23:50:30.869-08:00That&#39;s Kimi and Rufus, Maximus, and Julius.

I think ...About Tilapias and other non native fish:<br />I think the basic problem is that current legislation allows the cultivation of non-native fish in cages networks only in environments where the NON NATIVE species is demonstrably established, which is not the case in most environments dammed in the country, especially in the basins in the West and North portions of the Brazil.<br />Apart from this obvious mismatch, the major concern is about the possibility of massive releases of non-native fishes into Brazilian ecosystems. There are numerous scientific publications showing that negative impacts follow the establishment of non-native fish, including impacts caused by tilapia (a target species) in Brazilian aquatic ecosystems (e.g. Vitule 2009 and references therein), problems neglected in the law project (PL). Especially, PL neglected broad and basic aspects concerning fish invasionlike: there is no safe confinement in aquaculture, and the activity has been considered the main vector releasing non-native organisms around the world (Naylor et al., 2001). Fish escapes are inevitable, and cage aquaculture may create a constant flow of propagules into the wild , establishment, spread and invasions. Certainly, aquaculture may affect invaders dynamics, which in turn determine impacts. Finally, cages will be installed in reservoirs, environments that facilitate the invasion process (Johnson et al. 2008), so establishment, dispersion and impacts will be magnified triggering to colossal invasion events across South America, because reservoirs are in all large basins of the continent and fish do not recognize political borders. <br /><br />If the real danger of species introductions is minimized<br />because of insufficient and unreliable data, or misguided<br />ecological pragmatism, carte blanche is in fact provided<br />to decision-makers or organizations who think only<br />about immediate profit that introductions can bring,<br />without considering longer term losses. Those losses<br />will be tremendous and experienced by all future<br />generations, especially those who live in megadiverse<br />tropical countries.(Lövei at al 2012).<br />Jean Vitulejeanvitulehttps://www.blogger.com/profile/00685787198546108318noreply@blogger.com
